  The SAP error message RSDME219, which states "Duplicate source reference names not allowed," typically occurs in the context of SAP BW (Business Warehouse) when you are trying to create or modify a data source, InfoObject, or similar object that has a naming conflict with an existing object.
  Cause:
  The error is caused by attempting to create a new object (like a data source or InfoObject) with a name that already exists in the system. SAP requires that all objects have unique names to avoid confusion and ensure proper data processing.
  Solution:
  To resolve this error, you can take the following steps:

  You can use the search functionality to find objects by name.
  
  
  
  Rename the New Object:
  
  If you find that the name is already in use, consider renaming your new object to something unique. Ensure that the new name adheres to SAP naming conventions.
  
  
  
  Delete or Modify Existing Object:
  
  If the existing object is no longer needed, you can delete it. However, be cautious with this approach, as it may affect other processes or reports that rely on that object.
  Alternatively, you can modify the existing object to change its name if it is appropriate to do so.
  
  
  
  Check for Transport Requests:
  
  If you are working in a development environment and the object is part of a transport request, ensure that the transport request is not causing conflicts with existing objects in the target system.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific object type you are working with for any additional guidelines or naming conventions.
